WILLIAM D. MQCLAIN, OF ST. LOUIS, MISSOURI, ASSIGNOR T0 WALIDO FORD, OFST. LOUIS, MISSOURI.

SHOE-MACHINE.

To all whom it may concern Be it known that I, WILLIAM D. MOCLAIN, acitizen of the United States, residing at the city of St. Louis, Stateof Missouri, have invented a new and useful Shoe-Machine, of which thefollowing is a specification.

This invention relates to improvements in shoe machinery, and moreparticularly to an apparatus for the lining of inner soles for shoes,andone of its objects is to produce a machine of the charactermentioned, whereby the fabric lining for the inner sole of shoes may becut to the proper length,

for the varying sizes, thereby eliminating considerable waste entailedby the present usual methods.

Another object is to provide automatic means for aflixing the fabriclining to the inner sole.

Another object is to provide means for pressing the fabric after it hasbeen secured to the sole, so that it will conform to the contour of thesurface to which it is aflixed.

To these and other ends I have designed, combined and arranged theseveral cooperating parts in the novel manner hereinafter described inthe specification and illustrated in the drawings, in which- Figure 1 isa side elevation of a machine embodying my invention. Fig. 2 is a rearelevation of the machine, a part of the fabric strip being broken toshow a part of the operating mechanism. Fig. 3 is a plan view of mymechanism. Fig. 4: a view showing the details of certain of the parts;the fabric feed, cutter and table being shown in Vertical section. Fig.5 is a detail View illustrating the mechanism for raising the cutterframe. Fig. 6 is a view illustrating the mechanism for lowering thecutter frame. Fig. 7 is a detail sectional view of a part of the fabricfeed mechanism. Fig. 8 is a side elevation of the same parts.

In the embodiment of my invention illus trated 1 indicates the frame orstand, to the upper part of which is suitably secured a table 2. Guideplates 3 are arranged to be adjustably secured to the upper face of thetable. These plates may be adjusted so as to conform to the front edgesof soles of different size and shape or other articles in the mannershown in dotted lines in Fig. 3. The simplest and most convenient mannerof securing said plates 3 to the table 2 is Specification of LettersPatent.

to form an outwardly extending lug 4 on the 7 side of each of the plates3, said lugs 4: having elongated slots therein, against the sides ofwhich the head of a machine or thumb screw will bind when screwed intosuitably arranged threaded holes in the upper face of the table 2. Theknife or cutter j frame 5 is slidably mounted on vertical shafts 6mounted on the frame 2 at each side thereof. As said shafts 6 constitutethe supports and guides for the knife frame they are arranged in truea-linement, and are bolted or otherwise rigidly secured to the table 2,so that the movable cutter element 7 carried by the frame will work truewith the cooperating cutter element 8 bolted or otherwise rigidlysecured to the upper face of the table 2.

A forwardly extending arm 9 is rigidly secured to and is carriedby theframe 5.

An element 10, of a shape to conform with may be adjusted by raising orlowering the stem 11, and may be conveniently held in the differentadjustments by passing a cotter pin 12 through one of the several holes13 in the upper part of the stem adjacent to the upper face of the arm9.

A fabric roll 14 is removably mounted in brackets 15 at the rear of theframe or stand 1. In the use of the present mechanism for lininginnershoe soles, it is contemplated I that the fabric be treated withsome adhesive material, such as rubber'cement, on its inner surfacebefore being placed in the roll. In the operation of the machine thestrip of fabric passes over the feed roller 16, which has inlaid in itsperiphery two serrated rings 17, against which the fabric is held by twogrooved rollers 18, carried by arms 19, carried on a transverse shaft 20supported by extensions 21 on the table 2. These arms are actuateddownwardly by springs so that the fabric will be automatically fed tothe table as the feed roll is rotated by mechanism hereinafterdescribed.

The feed roller 16 is rigid on the shaft 22, which is mountedtransversely of the machine in hearings in the uprights 23. One end ofthe said shaft 22 extends beyond the frame of themachine, and carriesthe part of feed mechanism illustrated in detail in Figs. 7 and 8. Theratchet wheel 24 is rigid with the shaft 22, while the gear wheel 25, oflarger diameter, is loose on the shaft. On

10 the inner surface of the gear wheel 25 is arranged the snap pawl 25,which, when the gear wheel 25 is rotated in one direction, Will travelover the face of the teeth on the ratchet wheel 24, and when rotated inthe 5 opposite direction will lock the two wheels 24 and 25 in anobvious manner and thereby rotate theshaft 22. The rock arm 26 ispivoted at the side of the table 2, as clearly shown in Fig. 1. The saidarm 26 carries at its inner end the segmental rack 27, which rack mesheswith the gear wheel 25. The mechanism for rocking the arm 26 comprises aplate 28 carried on a shaft 29 journaled in the frame of the machine.The shaft 29 has suitable gear connection with the main or driven shaft30, comprising the gear wheels 31, 32, 33 and 34, through which rotationfrom the main shaft is imparted to the said counter shaft 29. The plate28 is operatively connected to the arm 26 by the link 35, pivotedadjacent to the outer end thereof, and eccentrically to the plate 28.The pivot point between said arm 26 and the link 35 may be readilyadjusted by operating thumb 35 screws 36 extending into a slot 37 in thearm, or by other convenient mechanism for the same purpose.

It will be obvious that as the ivot point between the arm 26 and link 35is dlianged the 40 are described by the rack 27 will be varied, and thatas the end of the link- 35 is moved toward the fulcrum of the arm 26,the extent of rotation imparted to the gear 16 will be reduced, and viceversa as it is moved from the fulcrum of the arm. Thus the amount ofmaterial from the roll 14 fed to the table 2 maybe Varied, andpredetermined by the simple manipulation of the adjusting means 36 orits equivalent.

The movable cutter element and presser are operated throughthe mechanismillustrated in detail in Figs. 5 and 6. The arm 38 is pivoted to theshaft 39, mounted transversely of the machine in brackets 40 at thefront of the frame. Said arms 38 are provided with a vertical extension41, having a slot 42, through which the transverse shaft 29 passes, sothat the arm may have vertical movement. The arm 38, on one side .and

adjacent to the bottom thereof, carries a roller 43, and on the oppositeface adjacent to the upper extremity of the vertical extension 41 asecond roller 44. The cam 45 is rigid on the shaft 29 and is arranged tocontact with the roller 43, with which it cooperates to force the arm 43downwardly, while the cam 46 also rigid on the shaft 29 contacts withthe roller 44 with which it cooperates to raise the arm 38. By links 47the inner end of the arm 38 is connected to the cutter frame 5. Thus itis obvious that the cutter frame and its carried parts will. beintermittently raised and lowered by the cam surfaces, as the shaft 29is revolved by its gear connections with the main shaft 30. Usual beltpulleys 48 on the main shaft are provided, which may be driven bysuitable power transmission belts, from a power shaft (not shown) aswill be readily understood.

The operation of the mechanism is as follows: The roll of fabric isplaced in the brackets at the rear of the machine, having beenpreviously treated with some adhesive material. The fabric strip is thencarried over the feed roller, and the supplemental rollers are allowedto rest upon the upper surface of the fabric. By adjustment of the pivotpoint between the arm 26 and link 35 the exact amount that will be fedto the 0 table at each operation may be determined. As the main shaft isrotated the rack 27, through its connections therewith, is raised, thepawl 25 passing idly over the teeth of the ratchet 24. After reachingthe highest ,point in its travel which occurs at the instant the link 35is down, said rack 27 is pressed downwardly and the wheels 24 and 25 arelocked by the snap pawl 25 and the shaft carrying the feed roller isrotated suf- 10o ficiently to feed a predetermined length of fabric tothe table. In the meantime the shoe sole or other object to be operatedon has been placed flat on the table by the operator, at the properplace, which is determined by the guide plates The fabric coming fromthe feed roller passes over the object and the feed ceases as the objectis covered. During the operation just described the cutter framecarrying one of the knife elements and the presser element is raised toa considerable distance above the table. hen the fabric strip is broughtto the proper position the knife is lowered severing the fabric adjacent to the inner end of the object operated on, and the presserelement is brought down on the fabric over the object on the table. Thepressure continues and causes the fabric strip to closely and smoothlyadhere to the surface of the object operated on. The degree of pressuremay be regulated, and the speed of operation may be adjusted by suitablegearing, as willv be readily understood.

\Vhile I' have entitled my invention as re- 12.5 lating to shoemachinery, I am aware that the same mechanism may be readily adapted toother arts.

I am also aware that several changes in details of construction may bemade without departing in the least from the spirit and scope of myinvention. I do not limit myself, therefore, to details, but
